    • A positive displacement pump and thrust bearing assembly having a housing defining an internal fluid chamber having front and rear inner walls. A rotor having a front face and a rear face is positioned in the fluid chamber. Each of the faces of the rotor is spaced apart from a corresponding inner wall of the fluid chamber to define predetermined clearances therebetween. A shaft is connected at a first end to the rotor to effect rotation thereof. The shaft extends through a bore in the housing. The thrust bearing assembly includes an adjusting collar and a thrust bushing. The adjusting collar is attachable to the shaft and includes a central bore through which the shaft extends. The thrust bushing is secured within the bore of the housing by a locking ring that prevents longitudinal movement of the thrust bushing toward the fluid chamber. The adjusting collar is rotatable with the shaft and is in relative rotatable engagement with the thrust bushing. The adjusting collar and the thrust bushing prevent movement of the shaft and the rotor in a direction away from the adjusting sleeve and toward the rear inner wall of the fluid chamber such that the predetermined clearances between the faces of the rotor and the internal walls of the housing are substantially uniformly maintained as the rotor rotates.
    • 一种容积式泵和止推轴承组件,其具有限定具有前内壁和后内壁的内部流体室的壳体。 具有前表面和后表面的转子位于流体室中。 转子的每个表面与流体室的相应的内壁间隔开,以在它们之间限定预定的间隙。 轴在第一端连接到转子以进行旋转。 轴穿过壳体中的孔。 推力轴承组件包括调节环和推力衬套。 调节套环可连接到轴上并且包括轴延伸穿过的中心孔。 推力衬套通过锁定环固定在壳体的孔内,该锁定环防止推力衬套朝向流体室的纵向移动。 调节套环可与轴一起旋转并且可与推力衬套相对旋转地接合。 调节套环和推力衬套防止轴和转子沿着远离调节套筒并朝向流体室的后内壁的方向移动,使得转子表面和内壁之间的预定间隙 壳体在转子旋转时基本均匀地保持。

    • A flexible shaft coupling device having two hubs with jaws extending from each hub toward the other hub. A flexible elastomeric belt or cushions fill the gaps between adjacent pairs of jaws. A retaining ring is mounted around the belt or cushions to keep the belt or cushions securely in place. There are a plurality of locking pins adjacent to the edges of the retaining ring and preferably on the interior surface of the ring. These are received in grooves cut in the exterior surface of the belt. When the retaining ring is placed over the belt, the belt is retained between the locking pins. Raised portions or nubs are placed at the entrance and exits of the grooves so that when the ring is rotated with respect to the belt, the locking pins pass over the nubs to securely lock the retaining ring around the edges of the belt. Alternatively the edges of the belt or cushions are tapered to engage the pins in locking engagement.
    • 一种具有两个轮毂的柔性轴联接装置,其具有从每个轮毂向着另一轮毂延伸的夹爪。 柔性弹性带或垫子填充相邻的夹爪对之间的间隙。 保持环安装在皮带或垫子的周围,以保持皮带或垫子牢固到位。 存在与保持环的边缘相邻并且优选地在环的内表面上的多个锁定销。 它们被容纳在带的外表面上切割的凹槽中。 当保持环放置在皮带上时,皮带保持在锁定销之间。 凸起部分或凸起被放置在凹槽的入口和出口处,使得当环相对于带旋转时,锁定销越过凸块,以将保持环牢固地锁定在带的边缘周围。 或者,带或垫的边缘是锥形的,以在锁定接合中接合销。
